Unique Entity Identifier

The UEI number is how your city identifies itself to the federal government. All federal grant recipients must acquire a UEI number through SAM.gov.

If you have an active SAM registration, you already have a UEI. See: Where do I go on SAM.gov to view, manage, or deactivate an existing entity registration?

Grant sub-awardees may only need a UEI, not SAM registration. See What's the difference between only getting a Unique Entity ID and registering your entity?

As of April 4, 2022, the DUNS number has been replaced by the UEI and all applicants, current grantees and subgrantees must use UEI on all grant applications and reporting forms. See DUNS to Unique Entity ID (SAM) Transition.
